REFRIGERANT PIPING CONNECTIONS
Special Applications
If an additional drain hose is necessary, the end of drain outlet must
be routed above the ground. Secure the drain hose appropriately.
When the Outdoor Unit is Installed Below the Indoor Unit:
1. Use a conduit, piping set cover, or bundle the (separately) insu-
lated refrigerant piping, the drain hose, and the communications /
connection (power) cable together.
2. Make sure to include some slack in the wiring. Wiring must be
installed in an upwards direction to prevent water from accessing
into the control box.
3. Secure the conduit, piping set cover, or bundle along the outside
wall using saddles or a similar type of piping support.
4. Seal any openings in the wall that are around the piping.
